DESCRIPTION OF THE PREFERRED EMBODIMENTS

Advantages and features of the inventive concept and methods of accomplishing the same may be understood more readily by reference to the following detailed description of embodiments and the accompanying drawings. The inventive concept may, however, be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein. In the drawings, the relative sizes of elements should not be construed as being limited to the proportion and arrangement relationship as shown in the drawings and may be exaggerated for clarity, without departing from the spirit and scope of the present invention.

FIG. 2 is a first schematic view of an assembled cup structure in accordance with a first embodiment of the present invention. FIG. 3 is a second schematic view of the assembled cup structure in accordance with a first embodiment of the present invention. FIG. 4 is a third schematic view of the assembled cup structure in accordance with a first embodiment of the present invention. FIG. 5 is a first schematic view of the assembled cup structure in accordance with a second embodiment of the present invention. FIG. 6 is a second schematic view of the assembled cup structure in accordance with the second embodiment of the present invention. One of the features of the present invention is that the assembled cup structure is a dual-layer structure. One cup body can be stacked and disposed in the other cup body easily. When in use, the user just holds the outer cup body. A beverage is filled in the inner cup body. Through the space between the two cup bodies, the present invention provides a better thermal insulation effect, preventing the filled beverage from scalding the user. Another feature of the present invention is that portions of the two cup bodies are attached to each other closely, such that the beverage won't flow to the space between the two cup bodies when the beverage in the inner cup body is spilt.

In detail, as shown in FIG. 2 to FIG. 6, the assembled cup structure of the present invention comprises an outer cup body 10 and an inner cup body 20. The outer cup body 10 is formed with a first curved portion 12 on an inner wall thereof close to an outer cup mouth 11. An end edge of an inner cup mouth 21 of the inner cup body 20 is formed with a contact portion 22. The contact portion 22 holds against the first curved portion 12 of the outer cup body 10. Thereby, the inner cup body 20 is disposed inside the outer cup body 10. A space is defined between the bottom of the inner cup body 20 and the bottom of the outer cup body 10. Preferably, the distance A from the position where the first curved portion 12 and the contact portion 22 contact with each other to the outer cup mouth 11 of the outer cup body 10 is 11 mm to 16 mm. When the user drinks the beverage, he/she can feel the temperature of the beverage with his/her lips, avoiding the beverage from scalding the lips, but not limited thereto.

In the first embodiment, the first curved portion 12 of the outer cup body 10 may be a stepped configuration. As shown in FIG. 3 and FIG. 4, the stepped configuration includes a stepped surface 121 which may be concave or flat. The contact surface 22 of the inner cup body 20 may be held on the stepped surface 121. In a second embodiment, the first curved portion 12 may be an annular groove, as shown in FIG. 5 and FIG. 6. The inner cup body 20 is retained in the outer cup body 10 through the first curved portion 12 in the form of an annular groove to engage with the contact portion 22.

Furthermore, the outer cup body 10 is formed with a first mating portion 13 beneath the first curved portion 12. The inner cup body 20 is formed with a second mating portion 23 on an outer wall thereof beneath the contact portion 22. The second mating portion 23 is attached to the first mating portion 13 of the outer cup body 10 closely. This design can avoid the filled beverage from spilling and flowing to the space between the inner cup body 20 and the outer cup body 10. The first mating portion 13 and the second mating portion 23 may be bevels having a same slope. Preferably, the mating length C of the first mating portion 13 and the second mating portion 23 is 1 mm to 4 mm, but not limited thereto.

Besides, the outer cup body 10 is further formed with a second curved portion 14 beneath the first mating portion 13. The inner cup body 20 is formed with a buckle portion 24 beneath the second mating portion 23. The buckle portion 24 leans against the second curved portion 14. Thereby, the retaining strength between the inner cup body 20 and the outer cup body 10 can be enhanced, avoiding the inner cup body 20 from slipping out of the outer cup body 10. Preferably, the distance B from the position wherein the first curved portion 12 and the contact portion 22 contact with each other to another position where the buckle portion 24 and the second curved portion 14 engage with each other is less than 10 mm. This is beneficial to increase the strength of the outer cup body 10 and the inner cup body 20 when in use, but not limited thereto.

Preferably, the outer cup body 10 and the inner cup body 20 of the assembled cup structure of the present invention may be made of plastic, paper or a foam material. Preferably, the outer cup body 10 and the inner cup body 20 may be made of a transparent material or a colored material. Furthermore, the bottom of the outer cup body 10 may be formed an aperture 15. The aperture 15 is adapted to exhaust the vapor generated between the outer cup body and the inner body due to heat, so that the pressure between the inner cup body and the outer cup body can be balanced, avoiding the cup bodies from being buckled and deformed.
